PUMP. i

To all whom/t may concern; Be it known that I, loi-IN in the county of Albany and State ofNew York, have invented certain new and useful Improvements in Pumps, of which the following is a'specification.

My invention relates to improvements in pumps, the present embodiment 4ofthe invention relating more particularly to what may be termed a steam and vacuum operated pump. Y

It will be apparent, however, and should*- be understood, that the principles ofthis invention may be readily applied to orincorporated in various analogous structures,

inner and outer chamber formingr vessels, the walls of the inner vessel being formed or" such as engines, or the like, and are capable of la relatively wide use and application.v

The primary obj ect of the invention is the provision of a generally improved pump of the general character indicated which will be exceedingly `simple in construction, cheap of manufacture and efficient in use.

A further` and very important object is the provision of a pump of this class in.`

which the working-impulses will be automatically produced through the successive power of steam and vacuum produced in a noveland improved manner in a vaporizing andV condensing chamber and a surrounding heating and cooling chamberywith a :minimum consumption of liquid and fuel and a maximum'.amount of power]r f. A still further object Vis the provision of a novel construction and arrangement ofrelatively thin heat conducting materialand the walls of the outer vessel being of relatively ixed heat .insulating rmaterial, together with improved intermittently operating liquid cooling siphon mechanism and heat creating means communicating between the outer and inner vessels and adapted to alternately cool the inner vessel whereby -vaporizingf pressures and condensing and Referring tothe drawings, formingA a `partv Application .sied Decemberl 5, 191.9, serial No. 342,743.

vThe improved pump comprises a suitable supporting base l, mounted, in the present instance, on suitable supports or legs l?.

As ameans'of forming a suitable inner vessel forming a suitable vaporizing and condensing chamber, the basel, is provided..

with a central opening' 1b, and the `walls Vof.

the :vessel 1c, are'formedof relatively thin heat conductingmaterial,the lwalls 'of said inner vessel, in the present instance, being n of substantially' semi-spherical shape, as. shown, and conjointly with the-supporting base 1,. forming a liquid vaporizingvfand condensing chamber 1d'. preferably provided with a subj acent liquid supply head -or cylinder 2, the latter being` adapted to be lsupplied througha suitable inlet pipe 3, communicating with a main or valved inlet pipe 4t, communicating with av suitable source of'liquid supply. Y

The inlet pipe A, is provided below the level of the conduit pipe ,3, with afcheck valve A?, so Vas to permit the flow of liquid into theV 'supply head 2, and chamber l?, and' prevent retrograde' movement of the liquid therein yduring the working'impulse of `the pump through steam pressure, .as

hereinafter explained, and when the liquid flows out ofthe pipe .3, into,thedischarge .pi'per5,` the 'latter beingprovided with a check valve, immediately above the common liquid pipe 3. l

As a means of initially filling the vaporizf ing and vcondensing .chamber ld, vof the inner vessel 1, the base member 1, is providedl with a vent pipe 6, communicating with the The chamber 1d', is'V 4vessel 8, and pipes t upper portion of the chamber 1d,'and providedat its lower end with a valve 6a. The

base 1, is provided with a second openingu with liquid by opening the valve 6, ofthe vent .pipe 6, Vand pouring liquid into 'the V chamber through the medium Aof the funnel "b and 7 leading into the b chamber 1d, the vent pipe 6, permittingthe escape of air while the liquid is Vbeing filled to substantially the level indicated in Fig. 1, of the drawings, after. which the-valves 6a Hand 7a are closed.

As a means for forming al combined heating and cooling chamber about the walls of the inner vessel 1c, an outer similarly shaped vessel \9, is provided,'the walls ofthe vessel .9, being spaced from the walls 1c, forming a surrounding heating and cooling chamber 9a. The walls of the outer vesselare 'preferably heat insulated .by providing inner' and outer walls with anrinterposed filler of heat insulating material i9, such as fire clay, mineral wool, asbestos, or the like. l

lAs a means of heating the wallsvof the inner vessel 1C, for 'the generation of steam or vapor, the base of the heating and cooling chamber 9, isV provided with a Vaporiz- 'to a tank 10, the iow of liquid fuel supply Ving coil 10, Vsupported on suitable-brackets 10a, and communicating with a suitable Vsource of liquid 'fuel supply through the mediumV of a suitable feed pipe 10b, leading being controlled through the medium of a valve 10d. VAfter the liquid fuel is vaporized inthe vaporizingl coil 10, it passes into af burner coil 10e, the branches'of such coil extending about'the outer vessel and being provided with a series of burners 10f, adaptf ed'to discharge into a plurality of mixer Y openings 10g, formed `through the walls of the outer vessel. It will be obvious that the flames issuing from the burners 101, through the mixer openings 10g, will be discharged over the relatively thin walls of ther inner vessell".

. The terminal 1 burner pipe 10e, are provided with terminal lugs 10h, provided with openings adapted to beV fitted over supporting stems 11, the latter' forfthe burners 101', in supporting combus-V tion inthe heating chamberf9a, and'alsorproviding an inlet'for the discharge ofliquid over the innervessel 1C, for cooling the latq 1 ter and, condensing the steam or vapor and forming a vacuumA therein, the topof the outer vessel is provided withl 'a lcombined portions V'of the branchy Y upwardly into the inner vessel. action the flow of liquid through the siphon flue and liquid inlet opening 12., the latter being formed by means of a suitable funnel shaped casting and the casting being provided with ra bracket 12a, adapted to removably receive and contain a siphon pipe 13,V the latter communicating with a siphon chamber 14, and the siphon chamber 14, being formed by means of a suitable vessel or container 15, mounted upon and communicating with the discharge pipe 5.

As a means of lregulating `the predeterminedv amount of liquidadapted to accumu-- late in the siphon chamber 14, before .the siphon 13, is brought into action, the top ofthe siphon vessel 15is'provided with an adjustably mounted vent andV gagepipe' 1 6, secured by means Vof a packing and a packino' nut 16a.

lhe liquid fuel supply tank 10de, may be f Y secured to the vessel 15, by means of clamping bands 17, surrounding the said tanks or vessels: and connected by means of connecting elements 17a.v i f In-view of the construction hereinbefore described, it will be understoodA that upon filling the inner vessel and .supply pipe with y liquid and igniting the burnersV lOf, that the flames from the latter directed over and against the relatively thin walls 1C, of the inner vessel will vaporize the liquidtherein, thereby causing an accumulation of steam or vapor and the pressure thereof will force the. liquid downwardly and f outwardly through the head or cylinder 2, the check valve 4, in the main inlet pipe L1, preventing any retrograde movement of the liquid therein, thereby opening the check valve .5?,

in the discharge pipe 5, and causing the;

liquid to flow upwardly and into the siphon chamberV 111,where1itY accumulates until it reaches the lower. end' of the vent :and gagepipe 16, and the siphon pipe 13, then being.

ios

brought into action lthe liquid will be .trans- K ferred from the siphon chamberthrough the liue and inlet opening 12, and. downwardlyl over thevrelatively. thin conductingwalls 1C, of the inner vessel vthereby cooling ythe latter.V and causing a condensation of the'vapor or steam Vand :creating a vacuum in the upper portion thereof. In lso doing the liquid passing `downwardly over the dome shaped walls 1c, will also cool the vaporizingcoil so thatlittle vapor will reach .the burners 10f,"and but little'flame issue therefrom. The condensation and vacuum thus produced will result in a reverse movement of the liquid to lill the vacuum thusy formed whereupon the valveV 4a', in the main inlet pipe 4c, will open to permit a flow of liquid through the pipe-3, into the cylinder 2, and During such from the latter through the discharge pipe 18, after which the heating and vaporizing action will again take place and the operation will be repeated as before described.
